Adidas Ultra Boost ST

adidas running is squeezing all the juice out of the Boost franchise. And based on results and sales, the Boost experience, the revolutionary cushioning system, is proving to be more than positive for the German company. In the first part of 2015, the UltraBoost model was presented on the scene as the top-of-the-line shoe that would mark a before and after when it came to running. Before the end of 2015, adidas released a new and improved update with the UltraBoost 2016 version for neutral runners. Now, the latest from the three-stripes brand is called the UltraBoost ST (Stability) to position itself as the top-of-the-line cushioning shoe for pronator runners.

What's new in the adidas Ultra Boost Stability?

The UltraBoost ST still keeps the UltraBoost pattern as the base, and although there are few changes, they are significant enough to make the improvements noticeable. The styling and aerodynamics are the same, and one of the big changes comes from the 'Tuned Energy', whose focus is on a more structured midsole, as it includes up to 30% more Boost foam density. This provides greater energy return than the UltraBoost, with maximum cushioning and custom stability reinforcement.

But you have to turn the shoe upside down to notice the big new feature of the UltraBoost ST: its outsole. With the idea of achieving optimal transition and maximum grip, this new model of the Boost family incorporates a new web strectch design - filed and pivotless - and continental rubber.

Another aspect to take into account is the slight increase in weight, from the scarce 300 grams of the previous model to 346 grams in the men's version, and 278 grams for the women's model. Also new is the change in the drop. Used to a 10 mm drop, the UltraBoost ST is presented with a lowerdrop of 8 mm (heights 32 mm / 24 mm).

Perfect fit and natural stride

Also untouched is the Primeknit pattern, which ensures a perfect fit, and the rear Heel Counter, which provides greater stability in the heel area. In addition, the loose Achilles heel concept allows for a very natural stride. In addition, the Torsion System remains the transition element.

In short, and as adidas running points out, the UltraBoost ST is the most comfortable training shoe for overpronators created by the German company to date.
